MEANS FOR SEGURIN G AND ALINING MILL HEADSTOCKS, GABLES, AND LIKE MACHINE PARTS UPON THEIR SOLE OR FOUNDATION PLATES.

Application filed May 15, 1918.

To all whom it may concern:

Be itknown that I, THOMAS EDMUND HOLMES, a subject of the King of Great Britain and Ireland, and a resident of Glasgow, Scotland, have invented certain new and useful Means for Securing and Alining Mill Head-Stocks, Gables, and like Machine Parts upon Their Sole or Foundation Plates, of which the following is the specification.

The invention has for its object to provide simple, effective and exact means for alining and securing mill-headstocks, gables and like machine parts upon their sole plates or foundation structures.

According to the invention the sole plates or foundation structures, which may be of any convenient form, have upon them, and adapted to receive the housings or gables, entablatures transverse to the housings or gables and .having undercut lateral faces. On the lower faces of the housings or gables are recesses counterpart to but wider than the entablatures and having vertical sides. Within each recess and one at either side of the entablature and filling the space between its inclined Wall and the Wall of the recess, is a wedge-piece. These wedge-pieces are drawn into place by bolts or other convenient means, so locating the housings upon the base entablatures. The housings may additionally be secured in place by foundation bolts passing through them and the base entablatures. The inner walls of the housing recesses are of course fitted upon the upper faces of the entablature.

Figures 1 and 2 on the accompanying sheet of explanatory drawings are elevations at right angles to each other of parts of a mill headstock or housing and its foundation structure sufficient to show a simple example of the invention.

As shown in these drawings the sole or foundation device consists of a box girder A transverse to the headstock B. On the upper side of the girder there is formed an entablature having undercut lateral faces C,

Serial No. 234,782.

D. Jaw-like projections E, G, depending from the under side of the headstock B form a recess wider than the entablature faces and have vertical sides. Wedge pieces H, J are fitted between the vertical and inclined faces, and are drawn into position by vertical bolts K passed through them and the headstock jaws E, G, so locating the headstock upon the entablature. Through the headstock B and through the girders A there may be passed the main holding down bolts (not shown) securing the fitted inner surface of the recess upon the fitted upper face of the entablature.

What I claim is 1. Means for securing and alining machine parts upon their sole or foundation plates comprising on the sole or foundation, entablatures having undercut lateral faces, recesses wider than the entablatures on the lower face of the machine housings or gables, the recesses having vertical sides, wedge pieces between the vertical and inclined faces, and means to draw these wedge pieces into place and thus locate the housings upon the base entablatures, as described.

2. In the construction forming the subjectmatter of the foregoing claim hereof, foundations of box girder form, entablatures on the upper side of the girders, undercut lateral faces on the entablatures, a recess formed by jaw-like projections depending from the under side of mill-headstock, the recess being wider than the entablatures and having vertical sides, wedge pieces between the vertical and inclined faces and bolts passed through the wedges and the head- THOMAS EDMUND HOLMES.
